Yorkshire Naturalists at Huddersfield. 365 
Botany.—Mr. W. E. L. Wattam reports :—The long con- 
tinued drought was responsible for so few plants being noted 
in blossom. The first party, under the leadership of Dr. T. W. 
Woodhead, succeeded in finding Melampyrum pratense var. 
hians, and also the hairy form of heather, Calluna vulgaris var. 
incana. The new British heather Calluna vulgaris var, Evtkai, 
was not recorded from the moorland areas under investigation, 
but in all probability it will be found to occur on the intervening 
moorland between Harden Clough and its known habitat, 
Wessenden Head. The immense rush zones of Juncus effusus 
were assiduously worked for Juncus conglomeratus, but this 
particular rush was not found, and, as Dr. Woodhead sub- 
sequently pointed out at the meeting, with the aid of a graded 
series of specimen inflorescences of Juncus effusus, mistakes 
might easily arise in recording conglomeratus, unless special 
attention was paid to its distinguishing characteristic, the 
ribbed stem, the stem of Juncus effusus being smooth. The 
majority of the plants mentioned in the excursion programme 
were met with, and in addition, Stellaria neglecta (Weihe), 
Epilobium palustre, E. angustifolium, Solidago Virgaurea, 
Juncus bufonius, and Glyceria fluitans. An interesting form 
of Ranunculus repens, having foliage and flowers much reduced, 
was noted in the bog areas alongside the stream. Many trees 
of Pyrus Aucuparia were heavily laden with ruddy fruit, and 
Quercus sessiliflora and Castanea vulgaris were also noted in 
fruit. . 
The chief ecological features were pointed out, and ably 
explained by Dr. Woodhead, and his remarks thereon were 
greatly appreciated. 
Mr. Charles Mosley adds :—Although Quercus sessiliflora 
is the dominant species of oak in the Clough, it was interesting 
to note several trees of Q. pedunculata, some heavily laden with 
fruit, and one presented a peculiar elongated form of leafage. 
On the homeward journey, about half-way between Harden 
Moss and Holmfirth, I found, in a coppice, a tree of Q. imter- 
media, in fruit. 
Mosses.—Mr. C. A. Cheetham writes :—One noticeable fea- 
ture in connection with the mosses was the number of ab- 
sentees, the walls being altogether untenanted, and the common 
species of Tortula, Barbula, Bryum and Hypnum usually 
found on walls, were absent. The stream bed at Dolly Folly 
fall was the first place investigated, and shewed two mosses 
that were features of the watercourses seen during the day 
viz., Hypnum ochraceum end Hyocomium flagellare. Others 
were Fissidens pusillus, Brachythecium rutabulum, Hypnum 
falcatum, H. palustre. Further along the hillside a spring 
yielded Hypnum cordifolium and H. cuspidatum. On crossing 
the valley and entering the woods on the shale, Catharinea
